LAS VEGAS — NBA commissioner Adam Silver said Tuesday he was unsure whether Clippers owner Donald Sterling will be out of the NBA before the 2014-15 season.

As the ongoing legal battle between the banned Sterling and his wife Shelly continues, Silver, speaking at a press conference following the NBA Board of Governors meeting Tuesday afternoon, said he’s unsure the proposed $2 billion sale of the team will be completed before next season begins.

Shelly has taken her husband to court in order to try and get approval of taking control of the trust governing the team, allowing the sale of the Clippers to former Microsoft CEO Steve Ballmer to go through.

“No, I cannot say with certainty, and I can’t say with certainty because it’s in the hands of the probate court right now, and Donald is in the process of suing us for lots of money, and we’re defending ourselves against those lawsuits,” Silver said.

“The only thing I’ll say, and I appreciate that Kevin Johnson, who’s been representing in essence the players in this matter and direct discussions with the players and the Players Association understand it’s very difficult to say anything with certainty in a situation like this. I can say with certainty we are doing everything in our power to move Donald out as an owner in the NBA, and as I said, if the probate ruling doesn’t go in our favor, we’ll recommence our procedures under termination.”

Silver also said the league’s new centralized replay system will be put into use beginning with WNBA games in September and in preseason games in October.

Silver said he expected it to be fully operational by the start of the NBA season this fall.

“In essence, it’ll give our officials the assistance of a replay center in Secaucus, New Jersey, where they will be able to queue up the plays for the officials who will then review them,” Silver said. “The decision will still lie with the officials at the game on the court. They will have the ultimate decision on every call.”

The goal for the new system, according to the league, is to try to streamline the process and speed it up in order to try and limit the amount of time spent waiting for the officials to make decisions on calls during games.

By having the centralized replay system, when the officials walk over to the monitor and begin reviewing the play in question, the replay center will have already picked out the best review angles for the officials to look at. That should help speed up a process that, until now, has relied on the officials having to ask to see different angles.

The league already has begun adding additional cameras to arenas around the league, in order for all 29 NBA arenas to have a minimum number of them to meet the league’s criteria. The replay center will also have the ability to provide side-by-side shots for officials to look at.

Silver also said expansion currently isn’t on the table, and there are no teams looking to move at the moment. He also said the league approved an additional group of minority investors for the Bucks, but wasn’t sure if Packers quarterback Aaron Rodgers — who has been rumored to be interested in purchasing a stake in the team — was among them. … The commissioner also said he “really was moved” by LeBron James’ essay that outlined the reasons for his return to Cleveland.
